Arranged in the ball races are suitable anti-friction balls'which are engaged with the cones and in this connection it will be noted that after the cones have been properly adjusted on the shank with relation to the anti-friction balls 12 the knobs can be screwed upon the shank into engagement with the cones so as to lock the cones in position and at the same time to lock the knobs on the shank.

What is claimed is z- 1 1. In combination knob roses, a .shank passing through the knob threaded ends, said roses having ball races, balls therein, cones adjustably mounted upon the shank and adapted to engage the balls in the races, means for lockingthe cones in adjusted position on the shank, and means for holding the cones agalnst rotation while thelocking means is applied.

2. In combination knob roses having annular ball races therein surrounding a central aperture, a shank passing through the knob roses and having threaded ends, antifriction balls mounted in the races, cones threaded u on the shank and adapted to engage the alls in said races, knobs threaded on the shank and adapted to lock the cones in adjusted position, and means, for l1 1dingthe cones against rotation while the knobs are turned to locking osition.
